I had expected this might be the day when the hummingbird chicks would leave the nest... and it happened.  When I went out to pick up the morning paper at seven o'clock, both birds were sitting on the nest.  Only one was left when I checked a couple of hours later.  The second one stayed through the day and was still there at four o'clock this afternoon.  At five-thirty o'clock the nest was empty.  Of course,  tonight I am very happy that the little guys are so obviously healthy and were ready to set off into the big world on their own, but I admit to feeling somewhat bereft.
